 1. 1-1. f. 45. S. glabra, nobis, inLond. Journ. of Bot. vol. iii. p. 647. 



Hab. Lord Auckland's group and Campbell's Island ; on the trunks of trees and on rocks in moun- 

 tainous places, very abundant. 



Au exceedingly variable plant, of which we have added a character, that of Delise being imperfect. The most 

 obvious specific distinction lies in the pubescent apothecia with fimbriated margins to the cups, to which may be 

 added, the pale colour, and the wrinkled margins of the lobes, which are sometimes extremely concave. In alpine 

 specimens the thallus is often quite smooth underneath, with the margins singularly crumpled. The colour varies, 

 underneath it is of all shades, from black to a dirty yellow. Cape Horn and Falkland Island specimens are more 

 plane, with the lobes and apothecia larger. 



4. Sticta cellulifera, Hook. fil. et Tayl.; thallo stellatim expanso subdichotome ramoso fusco v. flavo 

 olivaceo saepe virescente glabro profunde reticulatim lacunoso rimis albidis, subtus fuliginoso tomentoso api- 

 cibus loboriun flavescentibus, lobis ktiusculis rotundatis angulatisve subacutis obtusis retusisve, cyphellis 

 parvis flavis, apotlieciis plurimis plerisque marginalibus, disco atro piano demum concavo, marginibus integris 

 crenulatisve inflexis. 



Hab. Lord Auckland's group and Campbell's Island ; on the trunks and branches of trees, abundant, 

 also on the mountain rocks. 



We know of no single character by which this form, which is as variable as any of its congeners, may be recog- 

 nized. In its normal state the whole frond is fully a span across, all parts of it rugose with deep lacunae ; specimens 

 from the woods are of a lax habit, with lobes an inch broad, of a pale brown or yellow beneath ; those from the 

 mountains, again, are deep olive green and almost black beneath, with the lobes short and round, and the cyphellae 

 of a bright yellow. In many respects it is very closely aUied to the S. carpoloma, Debse, which, according to Mon- 

 tagne (whose authentically named collection of Sticta is the completest I have seen), has the apothecia invariably mar- 

 ginal. The present plant includes in part both S. impressa and S. cellulifera, of the ' London Journal of Botany.' 



5. Sticta Menziesii, Hook. fil. et Tayl.; thallo stipitato valde coriaceo obovato-cuneato ecostato flavo- 

 fusco subtus brunneo, laciniis plamusculis lobatis retusis supra glaberrimis lsevibus subtus puberulis, cyphellis 

 immersis luteis marginibus elevatis, apotlieciis sparsis atro-fuscis, disco piano demum concavo, marginibus 

 tenuiter inflexis. 



Hab. Lord Auckland's group ; on the trunks of old trees. 



Discovered by Mr. Menzies in Dusky Bay, New Zealand. Very distinct from S.filiciiia, of Acharius, in the 

 ecostate frond, very thick texture, and dark coloured apothecia. Mr. Menzies' specimens have rather broader lobes, 

 but do not otherwise differ from those gathered in Lord Auckland's group. The S. httifrons, A. Rich., is also eostate, 

 and of a different colour, with small pale yellow-red apothecia. The present is in New Zealand probably confined 

 to the southern extremity.
